Wiring for a ‘98 232

JeffH

Does anyone have a wiring schematic or know if the circuit for the transom shower water pump includes a relay or if it’s just straight switched? And if there is a relay where would they have hidden it?

Just a float switch inside the pump

Or a pressure switch

@JeffH normally a pressurized water system (with tank etc.) has a central pump that turns on when it senses the pressure in the system is low.  If your shower gets water from a tank and central system, then the central pump is where it's all happening.

It is just straight switched. If it is a cuddy, the switch is above the sink. Not sure where the switch is on an open bow. My 98 232 was a cuddy cabin.

Thanks for the info, mine is an open bow and the switch is on the dash. I’m making some changes to that circuit and think adding a rely to protect the wiring and switch seems wise. 

Stodge

@JeffH If the pump is directly switched it should have an in-line fuse or circuit breaker.  Seems a relay on top of that might be a bit of over kill.

Hmmm very true

I was thinking of installing a small 12v air compressor to blow up all the kids toys and thought the rely would protect against any starting surge.

I applaud your concern for safety.

I've used the cigarette lighter socket at the helm to run a compressor without issues.  That circuit (at least in my boat) is on its own breaker at the helm.

Haven’t brought the boat to the house yet but I do have a lighter socket at the helm as well. Don’t remember about a breaker there but it makes sense.
